The 100-D115KA11 contactor is a non-reversing contactor that is intended to operate in the automation industry. This contactor has been designed by Allen-Bradley in the Bulletin 100-D series. This contactor can perform heavy-duty switching operations in applications where motors are involved. This contactor can withstand operations at 240 Volts AC voltage and a frequency of 50 to 60 Hertz. The maximum current rating has been calculated at 2 different temperatures, and the contactor can operate at 250 Amps at 40 degrees Celsius and 115 Amps at 60 degrees Celsius. If the operating temperature is higher than 60 degrees Celsius, the current will need to be derated by at least 15 percent to prevent contactor damage. The Allen-Bradley 100-D115KA11 non-reversing contactor comes with one normally open auxiliary contact and one normally closed auxiliary contact. The main contacts come with conventional coils that are gold-plated. The contactor operates with 3 poles as its main contacts.

The Allen-Bradley 100-D115KA11 Bulletin 100-D non-reversing contactor can be installed on a panel in a location that does not exceed an altitude of 3000 meters above sea level. This contactor has been manufactured out of components and materials that do not cause any harm to the environment. The Allen-Bradley 100-D115KA11 non-reversing contactor can provide mirror contact performance with its auxiliary contacts which keeps the status of the normally closed auxiliary contacts on the contactor the same even when a power contact welds. The main applications for this contactor are hazardous motion loads that require feedback, energy isolating, and switchgear monitoring applications. This contactor can also be used in circuits where multiple contactors are used, mainly with those that use the same auxiliary contacts and those that have similar operating modes. This contactor is only compatible with non-reversing equipment because it is a non-reversing contactor.
